Fajitas are one of those easy and delicious weeknight meals that can be thrown together pretty quickly. I don’t like to go halfway with things though, so we’re really going all the way with flavor. Featuring steak that’s been perfectly marinated and crispy tasty toppings, this dinner is about to be your new all time favorite.

What Is A Fajita?

A fajita is traditionally just a Mexican dish that is made up of any grilled meat that’s served in either a flour or corn tortilla. The thing that really makes fajitas special are the spices used in it. You know when you’re at a restaurant and a sizzling, exciting plate is walked by your table, prompting everyone to ask: ‘what is that?’. Well it’s a fajita!

What Type Of Steak Is Best

Ideally I like to marinate my steak overnight to make it both tender and full of flavor. When using this method, you don’t have to shell out the big bucks on an expensive cut of meat. I just use skirt steak or flank steak and get perfectly tasty results!

Making Your Own Fajita Seasoning

This spice blend is an absolute staple in any pantry, even if you don’t cook Mexican dishes very often. It’s just so full of complex flavor, like sweet paprika, smokey cumin, and hot cayenne.

I made a quick and dirty fajita seasoning today for this dish but if you’d like to go full hog, feel free to ax the spices in the marinade for this special blend recipe right here on my other blog, Jo Cooks.

How To Make Steak Fajitas

Detailed measurements and instructions can be found on the printable recipe card at the bottom of the page.

Marinate the beef: Place all the beef ingredients in a ziploc bag, mix well and massage beef to coat. Refrigerate for at least 30 minutes to overnight (optional).
Cook the steak: Heat 1 tbsp of the olive oil in a large skillet over high heat. Drizzle 1 tbsp of olive oil over the skirt steak and rub it well. Add the beef to the skillet and cook to your liking, about 3 to 4 minutes per side for medium, rare, depending on thickness of meat.
Rest the meat: Transfer the beef to a plate and cover loosley with foil. Let the mat rest for 10 to 15 minutes before slicing into it. This will ensure all the juices stay in and don’t run out.
Cook the veggies: Heat the remaining 1 tbsp of olive oil in the same skillet. Add the onions, bell peppers and season with salt and pepper. Cook on high heat, until the onion and peppers begin to char. Transfer to a plate.
Finish the dish: Slice the steak against the grain thinly. Squeeze lime wedges over the steak before serving. Serve steak in tortillas topped with onion/pepper mixture and topped with your favorite fixings.

Cooking Your Steak To The Right Temperature

Not super familiar cooking with steak? Well I have an easy test to determine which temperature your meat is at without having to cut it open no matter the cut. It’s called the hand test:

First make the “okay” sign with your pointer finger and thumb. Now poke the fleshy part right under your thumb with your other pointer finger, that is how rare steak feels.
Next press your thumb and middle finger in the okay sign and feel that same fleshy part, that is how medium rare steak feels.
Press your ring finger and thumb in the “okay” sign and feel that fleshy part, that is how medium steak feels.
Now press your pinky and thumb together and feel the fleshy part, that is how well done steak feels.

Just press the middle of your steak as it cooks and compare it to that fleshy part of your hand right beneath the thumb and you’ll have a gauge of how your meat is cooking!

Of course, the most accurate way to tell if your steak is done is using a instant meat thermometer. Here’s a guide to help you out.
